The Brandywine Communications Model FDU-240 is a 2 input and 24 output frequency distribution amplifier that offers modern, often requested and reliable features. The base unit outputs twenty-four sine waves that are input directly from the rear panel to the transfer switch. For enhanced phase noise performance an optional clean up oscillator is positioned between the rear panel inputs and the inputs of the transfer switch. A clean up oscillator may be installed between both Input A and Input B inputs or only on Input A.
